Which of the following would be an appropriate improvised dressing for a bleeding wound?

Cloth scraps are an appropriate improvised dressing for a bleeding wound due to their ability to absorb blood, provide a barrier against contaminants, and help with wound closure. Clean cloth strips can be applied directly to the wound, and if positioned properly, they can apply gentle pressure to control bleeding. This material is commonly available and easy to manipulate for effective wound care.

Using clean cloth scraps is also preferable because they can be found in various forms, such as old t-shirts or other textile materials, and are generally more effective than non-absorbent materials. While the other options may not offer the necessary absorbency, support, or safety needed for wound care, cloth scraps serve the primary objectives of preventing infection, controlling blood loss, and allowing for easier dressing changes.
